Overview

Given a go.mod file, find all ‘replace` directives pointing to a path on the local filesystem outside of the current checkout, and return a hash mapping the original path to a hash of the path.

This lets us substitute all parts of the go.mod that are dependent on the layout of the filesystem with a structure we can reproduce (i.e. no paths such as ../../../foo), run the Go tooling, then reverse the process afterwards.
